People who regularly take proton pump inhibitors (PPIs) have less diversity among their gut bacteria, putting them at increased risk for infections like clostridium difficile and pneumonia, in addition to vitamin deficie...

In a study of nearly 2,000 adults, researchers found that a buildup of plaque in the body's major arteries was associated with mild cognitive impairment. Atherosclerosis is a condition in which fat, cholesterol and other...

Healthy cells reduce their growth when there is a lack of oxygen (hypoxia). This makes it even more surprising that hypoxia is a characteristic feature of malignant tumors. In two publications, researchers report on how ...

For many bacteria and parasites looking to get a load of the fresh nutritional bounty inside your body, the skin is the first and most important gatekeeper. Schistosomas, however, and burrow right on through. These water...

Structures of human mitochondrial aspartate/glutamate carrier regulatory domains reveal the nature of calcium-dependent conformational changes.

A new device that may result in more comfortable mammography for women has been created by researchers. According to a new study, standardizing the pressure applied in mammography would reduce pain associated with breast...

Using a new imaging technique, researchers have found that the biological machinery that builds DNA can insert molecules into the DNA strand that are damaged as a result of environmental exposures. These damaged molecule...

Expensive tests for measuring everything from sperm motility to cancer diagnosis have just been made hundreds of thousands of dollars cheaper by a Ph.D. student from England who hacked his own microscope.

Barriers to the sharing of public health data hamper decision-making efforts on local, national and global levels, and stymie attempts to contain emerging global health threats, an international team of researchers has a...

Public health researchers in Philadelphia looked at how neighborhood and community-level factors -- not just individual factors like diet, exercise and education -- influence people's diabetes risk. Their new study adds ...

Experimental anti-cancer agents PF-04691502 and PD-0325901 excel in lab tests against colorectal cancer models and enter phase 1 trial, scientists report. "This study demonstrates strong potential for this combination in...

Testosterone (T) therapy is routinely used in men with hypogonadism, a condition in which diminished function of the gonads occurs. Although there is no evidence that T therapy increases the risk of prostate cancer (PCa)...

Researchers have identified genetic markers that may help to identify individuals at risk for acute kidney injury (AKI) in the hospital setting. The study offers new clues about the development of AKI and could lead to p...

While wormholes are possible according to Einstein's theory of general relativity, it's unlikely that people will ever be able to travel through one, said renowned astrophysicist Kip Thorne of the California Institute of...

A new study finds a decrease in an emergent strain of methicillin-resistant S. aureus (MRSA) that is resistant to last line defense antibiotics. Researchers examined the prevalence of vancomycin-resistant Staphylococcus ...

Scientists have found a simple method to convert human skin cells into the specialized neurons that detect pain, itch, touch and other bodily sensations. These neurons are also affected by spinal cord injury and involved...

The search for a living laboratory model of Alzheimer's disease (AD) -- the so-called "Alzheimer's in a dish" --has a new candidate. Researchers report success in creating induced neurons that model Alzheimer's by starti...

(Brunel University) Expensive tests for measuring everything from sperm motility to cancer diagnosis have just been made hundreds of thousands of pounds cheaper by a Ph.D. student from Brunel University London who hacked...

Children born during or shortly after the 1997 El Niño, which saw 16 times more rain in northern Peru than usual, are shorter than they should be

Scientists believe that dark energy--the mysterious force that is accelerating cosmic expansion--makes up about 70 percent of the mass and energy of the universe. But because they don't know what it is, they cannot obser...

I may be biased1, but to me there is no disputing the fact that radio galaxies are the most extreme objects in the universe.Radio galaxies are recognizable by their enormous jets and lobes of radiating plasma, driven out...
